BEAM SUPPORT.

vApplication led February 27, 19,22. Serial No. 539,431.

T o all whom t may con'cern A Be it known that l, GEORGE Ansrr, a citi*Zen of the United States, residing at Paterson, in the county of Passaicand State of New Jersey, have invented certain new and usefulImprovements in Beam Supports, of which the following'isa specification.

This invention relatesto beam supporting means, as the means forsupporting the beam in warping machines, and particularly to beamsupporting of the class where there are two supports, one foreach endofthe beam, and one of these supports is revoluble in a bearing andserves to rotate the beam. Usually in these particular structures therevoluble beam support has an endwise bore forin'ing'a'seatfor onetrunnion of the beam, the other beam support-having afsocket in whichthe other beam trunnion may be dropped; andto introduceor remove beam,especially if it is heavy, requires three men, two to support the beamits ends and withdraw it from or introduce it into the bore and a thirdto shift the opposite supf port away lfrom or toward the revoluble Ysupport.I as the case may be. rl`he object of this invention is toconstruct the revoluble support and its bearing so thaty thecorresponding trunnion may be introduced into or removed from therevoluble support by a movement transverse instead of longitudinally ofthe beam axis and so that the bearing may, as usual, perform its part insustaining directly the load represented by the beam; To these ends, therevoluble support'is provided with a, .laterally open recess to receivethe trunnion and extending within the bearing and the bearing with aslot with which the recess may come into register to permit introduction`or removal of the beam, and in the support is an annular retainingmember revoluble around the axis of the support and having a lateralrecess forming` a seat for the beam and adapted on revolving said memberto stand in or out of registry with the recess of said support. Anotherobject is to provide means for preventing possibility of injury to anattendant due to his fingers projecting into the recess of the supportwhen the latter is rotating.

In the drawings,

Fig. 8 is a view showing 'partly in front elevation and partly insection, on the same scale, the parts appearing in Fig. 2;

f F ig, is a side elevation of the revoluble support kwith the retainingmember removed; and n Fig. 5 is asimilar view, showingvthe retainingmember in place and in section.

ff, is the beam and is its nonrevoluble support, having a crotch b toreceive one trunnion of the beam, as c. The revoluble support forreceiving the other trunnion of the beam consists ofA a shaft cl whichhas a two-armed yoke e thereon, the hub e of the yoke being keyed on theend of the shaft at f. The shaft has a fixed collar g thereon spacedfrom the hub between which and the collarv the shaft is journaled 'in abearing member 7L. lt is not material how themembers b and h aresupported, but, following a well known construction, they are in thepresent instance both shown slidablev on a e pair of horizontal rails z'which form a part of the machine frameand they are rigidly connected bya `rod j so as to form a unitary structure. Y Also, followingsaid wellknown construction. the shaft Z penetrates and is splined in asuitablerevoluble member 7c for rotating the same which is journaled in' theframe and may be suitably. drivenjfrom` vthe drive yshaft Z.

The revoluble support VZ-e is'formed with a laterally open recess mwhich reaches from the outer end of the hub c into the part of saidsupport ,immediately containedl within the bearing member 7L, and thisrecess 'is adapted to receive the right-hand trunnion c by simplydropping the` latter into the recess when the support is turned so thatthe recessy is upward. To permit the trunnion to enter or leave therecess the bearing member 7L has a slot a of approximately the samewidth as the recess m. By forming the re cess in the journal-portion ofthe revoluble support as well as in its hub portion e the trunnion ofthe beam maybe'made long enough so as to overlie the bearing member 7Lwhich thereby directly supports the loady represented by the bea-mandthe material wound thereon. l

The part'of the recess m which is contained within the yoke e isenlarged,.as at m', to form a cylindrical bearing, and in this isrevoluble a sleeve or annular retaining member 0 which is slotted or cutavvay from end to end, as at 0, its bore and slot forming a laterallyopen recess affording a seat for the trunnion Which is ush With the partof the recess m that is in the journalportion 01" the supporting member(Z-e. The sleeve is retained in the bearing m. by having acircumferential groove p in which is engaged the end of a pin g that isi'itted into the shaft d before the yoke e is keyed thereon. The sleeveis adapted to turn in its bearing back and orthy between definitelimits, at one of said limits having its slot 0 registering with therecess in the revoluble support, so that the trunnion may be introducedinto or removed from said recess7 and at the other of the limitsextending across the recess so that when the trunnion is in the recessit Will be retained therein by the sleeve (Figs. 2 and 5). The limitedrotary movement of the sleeve be accomplished by an arm r which projectsradially therefrom in contact with the face of the yoke c adjoining thebeam. said arm-having a post 5' thereon adapted to abut each arm of theyoke, t being a spring pin in the post which is adapted to override alug it on one ot' the yoke arms and by bearing endivise frictionallyagainst the same hold the sleeve in the closed position. y

@he beam may be connected to rotate vvith the revoluble support in anyWay, as by a strap o which connects one oil its yoke arms and a stud wprojecting from the beam.

When the beam is to be entered to or removed from the supports Zi andcZ-c the latter is turned to such a position that its recess m.coincides with the slot it of the bearing member 7L); the sleeve is thenturned so that its slot (see Fig. 2) registers with the registeringrecess of the support and slotof the bearing. The beam can then be movedto or from its seat Without endwise movement thereof and the incidentalshifting ot the support b toward and from the support d--a In order toprevent injury to the attendant in case his fingers should be placed invbearin0V a revoluble incense the recess m When it registers with theslot in the bearing member ft and the machine is being driven I providea guard or cover for the slot as follows: In order to resist thetendency of the Warp dra-ft on' their beam' to unship it the slot a isarrangedl at about forward from the top of the bearing member h. andthis guard or cover m is pivoted to said member on an aXis fz/ parallelWith that ot the revoluble support and relatively above the slot, in itsopen or uncovering position standing upright and having a bearingbackward against said member. lt has a lateral lug m arrangedeccentrically of its pivot y. On the hub e is arranged a' cam lug e intoWhose path of movement the lug as projects when the cover is open (Fig.2). es soon as the machine starts up this cam .a engages the lug ac',causing the cover n: to itall t0 covering position.

Having thus fully described my invention, what I claimV as new anddesire to secure by Letters Patent is 1. Beam supporting means includinga bearing, a revoluble support therein having a lateraliy open recessextending to its end and Within thebearing and adapted to receive thebeam trunnion7 the bearingl having a slot with which the recess isadapted' to register on revolving the support7 and a re'- taining memberrevoluble in and aroundthe axis of the support and having a lateralrecess forming a seat for the beam and adapted on revolving said .memberto stand in or out of registry with the recess of the support.

2. Beam supporting means including g, support therein having a laterallyopen' recess eXteiiding to its endv and Within the bearing and adaptedt0 receive the beam trunn-ion, the bearinghaving a slot with which therecess is adapted to4` register, and a cover on the bearing movablevinto covering relation to the slot and also to esoneri Ansar.
